Overview

Lain is a general-purpose mutation framework with heavy focus on using procedural macros for code generation. It currently supports the following major features:

• Fully recursive mutation. See Mutation.
• Binary serialization to big or little endian with per-field byteorder overriding. See Byteorder Overriding.
• Specifying min/max bounds for numbers, arrays, and vectors, as well as dynamic size constraints for vectors. See Derives.
• Mutating and serializing "union" types. See Unions.
• Bitfields. See Derives.
• Post-mutation fixups. See Mutation Lifecycle.
